Question

我是javascript方面的完全入门者，以及一般的编程知识。在线课程给我的任务非常复杂。

基本上，它被称为checks.js（因为它假定检查索引工作）应像这样工作：

// Built-in  Node.JS module for the check
var assert = require('assert');

// input your function
var addTime = require('./index.js');

assert.equal(addTime(12, 30, 30), '13:00', 'when 30 min is added to 12:30 we get 13:00');
assert.equal(addTime(23, 59, 31), '00:30', 'when 31 min is added to 23:59 we get 00:30');
assert.equal(addTime(11, 50, 61), '12:51', 'when 61 min is added to 11:50 we get 12:51');
assert.equal(addTime(23, 1, 80), '00:21', 'when 80 min is added to 23:01 we get 00:21');

console.info('OK!');

'index.js'由学生制作，模板如下：

/**
 * @param {Number} hours
 * @param {Number} minutes
 * @param {Number} interval
 * @returns {String}
 */
module.exports = function (hours, minutes, interval) {

};

所以我已经被编成这样的索引：

module.exports = function (hours, minutes, interval) {
    var allmin = (hours * 60)+minutes+interval;
    var allhours = Math.floor(allmin / 60);
    var fMin = allmin % 60

    if (allhours < 10) {
        allhours = toString(allhours);
        allhours = '0'+allhours;
    }

    if (fMin < 10) {
        fMin = toString(fMin); 
        fMin = '0'+fMin;
    }
    return allhours+':'+fMin
}

第二个是这样的

module.exports = function (hours, minutes, interval) {

   if (hours < 0 || hours > 23) {return false}
    var hours = Math.floor((minutes + interval) / 60);
    var minutes = (minutes + interval) % 60;

    if (hours < 10) {
        hours = toString(hours);
        hours = '0'+hours;
    }

    if (minutes < 10) {
        minutes = toString(minutes); 
        minutes = '0'+minutes;
    }

    return (hours+':'+minutes);
}

几乎相同，但是当我在终端中运行check.js来检查我的index.js时，我不断收到错误消息：

MBP-John-2:coursera JJ$ node checks.js
assert.js:86
  throw new AssertionError(obj);
  ^

真的需要帮助！

提前谢谢！
